Case Study Background
GlobalVoyage Travels, headquartered in Chennai, is India's fastest-growing travel conglomerate with operations spanning across 20+ countries in Asia, Europe, and North America. With 15,000+ employees worldwide, the company has established itself as a leader in leisure travel, corporate travel management, destination experiences, and hospitality services.
Mr. Rajan Krishnamurthy, CEO of GlobalVoyage Travels, recently unveiled "Vision 2035: Beyond Destinations" – an ambitious strategic roadmap focusing on personalized travel experiences, sustainable tourism, and digital transformation. "The travel industry is undergoing unprecedented transformation," emphasizes Mr. Krishnamurthy. "As we recover and grow, we face new challenges including managing peak traffic loads, ensuring system availability during high seasons, and providing seamless customer experiences across multiple channels."
Ms. Priya Sundaram, CTO at GlobalVoyage, has identified several critical infrastructure challenges:
- Peak load scalability challenges with traffic increasing 10x during holiday seasons
- Multi-cloud dependencies creating complexity in operations and cost management
- API sprawl with hundreds of third-party integrations for airlines, hotels, and payment gateways
- Need for global content delivery to support customers across 20+ countries
- Database performance issues during high-demand periods
- Inconsistent customer experience across web, mobile, and partner channels
- Rising infrastructure costs due to over-provisioning for peak seasons
"The travel and hospitality industry has unique infrastructure demands," explains Ms. Sundaram. "We need systems that can scale elastically, handle massive traffic spikes, integrate seamlessly with countless partners, and deliver fast experiences globally. Our current infrastructure wasn't designed for this level of complexity."
To address these challenges, GlobalVoyage has decided to embark on a comprehensive infrastructure transformation initiative.
Implementation Challenge
As the implementation consultant engaged to support this strategic initiative, you must address the following questions that incorporate both technical and organizational considerations.
Case Study Questions
- Elastic Scalability Architecture
GlobalVoyage experiences 10x traffic increases during peak seasons. How would you design an auto-scaling architecture that handles dramatic load variations while optimizing costs? Include specific patterns for application scaling, database scaling, and infrastructure automation.
- Multi-Cloud Strategy and Management
GlobalVoyage uses AWS for primary workloads, Azure for specific services, and GCP for analytics. How would you design a multi-cloud management strategy that provides consistent operations, avoids vendor lock-in, and optimizes workload placement? Include considerations for multi-cloud networking and cost management.
- API Gateway and Integration Architecture
With hundreds of third-party integrations (airlines, hotels, payment processors), how would you design a centralized API gateway architecture? Address challenges around rate limiting, circuit breakers, API versioning, partner onboarding, and monitoring across diverse integration patterns.
- Global Content Delivery Network (CDN)
Customers access GlobalVoyage from 20+ countries expecting fast load times. How would you design a CDN strategy and edge computing architecture that delivers optimal performance globally? Include cache strategies, edge security, and content optimization approaches.
- Event-Driven Architecture for Booking Systems
Travel bookings involve complex workflows with multiple steps and external dependencies. How would you design an event-driven architecture using message queues and event streaming that ensures reliability, handles failures gracefully, and maintains data consistency across distributed systems?
- Database Architecture for High Performance
GlobalVoyage's booking system experiences severe performance degradation during peak loads. How would you design a database architecture that handles read-heavy workloads, supports real-time inventory updates, and maintains consistency? Include caching strategies, read replicas, and database sharding approaches.
- Disaster Recovery and Business Continuity
Travel bookings are time-sensitive and revenue-critical. How would you design disaster recovery architecture with aggressive RTO/RPO targets? Include specific strategies for multi-region active-active deployment, automated failover, and data replication.
- Cost Optimization for Variable Workloads
Over-provisioning for peak seasons drives high costs. How would you design a FinOps framework that optimizes infrastructure spending for variable workloads? Include strategies for spot instances, reserved capacity, right-sizing, and automated cost controls.
- Observability and Performance Monitoring
Design a comprehensive observability framework for GlobalVoyage's distributed architecture. Include real-user monitoring, synthetic monitoring, distributed tracing across microservices, and business metrics dashboards. Address specific travel industry needs for booking funnel analysis and conversion tracking.
- Security Architecture for Payment Processing
GlobalVoyage processes sensitive payment and personal data across multiple regions. How would you design security architecture ensuring PCI-DSS compliance, data encryption, secure API communications, and protection against fraud? Include specific controls for multi-region operations.
Implementation Context
When developing your responses, consider these additional factors:
- GlobalVoyage faces fierce competition from both traditional travel companies and tech-driven aggregators
- The company is recovering from pandemic-related challenges and needs cost-effective solutions
- Economic volatility creates pressure to optimize infrastructure costs
- Customer expectations for fast, seamless experiences continue to rise
- Seasonal variations require flexible infrastructure that scales efficiently
Your implementation approach should balance technical excellence with cost optimization, ensuring that the infrastructure architecture delivers both exceptional customer experiences and sustainable economics for the travel business.
Evaluation Criteria
Students will be evaluated on:
- Understanding of cloud-native architecture and scalability patterns
- Ability to design for extreme load variations and cost optimization
- Practical approaches to multi-cloud and integration challenges
- Security architecture for payment and customer data
- Appreciation of travel industry context and seasonal business patterns
- Integration of modern practices like event-driven architecture and observability
